Summary
A new decision support tool significantly reduced hospital-acquired pressure ulcers (HAPU) and intensive care unit (ICU) length of stay. Nurses reported positive attitudes toward the Pressure Ulcer (PU) Manager intervention.
Area of Science:
- Medical Informatics
- Clinical Nursing
- Patient Safety
Background:
- Hospital-acquired pressure ulcers (HAPU) present a significant challenge in healthcare, contributing to patient morbidity, mortality, and increased costs.
- Existing prevention strategies for HAPU have demonstrated variable effectiveness, highlighting the need for improved interventions.
Purpose of the Study:
- To develop and evaluate a decision support intervention aimed at predicting HAPU.
- To assess the intervention's impact on HAPU prevalence and intensive care unit (ICU) length of stay.
- To examine user adoption rates and attitudes towards the intervention.
Main Methods:
- A Bayesian Network model, integrated into the Pressure Ulcer (PU) Manager application and linked to the electronic health record system, was employed.
- A comparative study design was used, with an intervention group (866 at-risk patients in surgical ICUs, 2009-2010) and a control group (348 patients, 2006-2007).
- HAPU prevalence was compared before and after intervention implementation, alongside user surveys to assess adoption and attitudes.
Main Results:
- The overall HAPU prevalence rate decreased dramatically from 21% to 4.0% in the intervention group.
- The ICU length of stay was significantly reduced from 7.6 to 5.2 days in the intervention group.
- The intervention group showed a tenfold reduction in HAPU [OR=0.1, p<0.0001] and a one-third reduction in ICU length of stay [OR=0.67, p<0.0001] after adjustments. User adoption of the PU Manager was high, with over 80% daily use in eligible cases.
Conclusions:
- The decision support intervention effectively reduced HAPU prevalence by tenfold.
- The intervention led to a significant decrease in ICU length of stay, by approximately one-third.
- Nurses exhibited positive attitudes towards the Pressure Ulcer (PU) Manager, indicating successful user adoption and acceptance.

01:18The Scientific Method in Nursing Process
The scientific method provides the foundation for any research. It is the most reliable and objective of all forms of gaining knowledge and guides in applying research-based evidence in practice and conducting future research.
When using research findings to change practice, one must understand the process used to guide a study. The scientific method is a systematic, step-by-step process that supports the data's validity, reliability, and generalizability. As a result, findings can be safely...

01:10Documentation of Nursing Diagnosis
The nurse documents nursing diagnoses and enters them into the patient record. The identified patient's nursing diagnosis is either written out with a plan of care or entered into the electronic health record.
In some settings, data-driven computerized decision support systems are in place, allowing for more accurate nursing diagnoses. The database within one of these systems includes diagnostic labels defining characteristics, activities, and indicators for nursing. A nurse enters assessment...
